Strange error about missing language

[alerque]

Sometime last week —and I can't correlate this with any change I'm aware of— SILE started throwing this warning pretty much any time I use it:

[1] [2] [3]
! Error loading language en-u-va-posix: /home/caleb/projects/sile//core/sile.lua:62: module 'languages/en-u-va-posix' not found: 
        no field package.preload['languages/en-u-va-posix'] 
...
<the usual list of search paths tried>

What page it falls on varies from document to document, but if nothing else it seems to give this at the end of a document if it hasn't happened before then. Sometimes it gets thrown many times per document.

I can't find anything in my environment, document or libraries where the string en-u-va-posix could be coming from.

You know, I would be debugging this the dumb-stupid way. At the top of core/languages.lua:loadLanguage, add if language == "en-u-va-posix" then SU.error("WHAT",1) end.

[alerque]

So this gets triggered any time I tag content as not having a language using \font[language=und]{...} or similar. Using xx or some other bogus value value produces the usual error about there being no language support file for xx, but passing und results in en-u-va-posix (which doesn't even match my system's locale setting).

[simoncozens]

The culprit is icu.canonicalize_language.

I think the warning will make this obvious now.

This seems to be still happening:

\begin{document}

\font[language=und]{Hello.}

\end{document}

Leads to:

This is SILE 0.9.5.1
<bug.sil>

! Error loading language en-u-va-posix: no support for this language
[1] 

However, the file seems to be generated correctly.

[alerque]

I routinely tag text in my books such as transliterations and pseudo-language words with und and the typesetting works fine. I've become blind to this error. As much as it makes more sense than the old error, I do think we should figure out a way to stop throwing it at all for text that is specifically tagged as being undefined. It's counter intuitive to have a language code you didn't specify showing up as an error.

This has been fixed.
